IMPROVEMENT IN` REFUSE-BURNING FURNACES.

Specification forming part of Letters Patent No. 116,829, dated July l1, 1871.

To all whom it may concern:

Be it known that we, GEORGE GooDsELL, BENNETT J. GooDsELL, and JOHN BEAN, Jr., of Pentwater, in the county of Ottawa and State of Michigan, have invented a new and useful Improvement in Refuse-Burning Furnaces; and we do declare that the following is a true and accu-- rate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon, and being a part of this specification, in which- Figure l is a perspective view of our furnace. Fig. 2 is a plan view of the furnace, showing the water-jacket around three sides of the fire-box. Fig. 3 is a longitudinal vertical section of the furnace, showing the deiiecting-plate and the illin g behind the plate.

The nature of this invention relates to the construction of a furnace in which to consume sawdust, edgings, and other refuse which is made by sawanills in the manufacture of lumber.

This invention consists of a fire-box with a flregrate and a plate at the back to throw the iiame up, with the necessary smoke-stack and air-fines, having a water-jacket on three sides of the {ireboX and extending over thefwhole top of the furnace, with the necessary supply and overiiow, pipes, with a feed-spout on the top of the fireboX through which the waste or refuse is placed or thrown into the reboX from an endless belt or apron leading1 from the mill; the whole forming a safe and economical means of getting rid ofthe waste, of which a large and cumbersome mass is made in the manufacture of lumber from the logs, as hereinafter more fully and substantially set forth.

Like letters designate like parts in each gure.

In the accompanying drawing, A represents the fire-box surrounded on three sides with the water-jacket B. The walls of this device are entirely constructed of brick, except the outer walls y of the water-jacket, which surrounds three sides of thefire-boX. B is a metallic pan having flanges projecting downward to fit over thewalls, thereby protecting these from the action of the weather, and is supplied with water in any convenient way. The outer walls d ofthe water-j acket may be made of wood or any other convenient material. The feed-spout C passes throught-he water and the bottom of the pan on the top of the rebox, and throws the fuel or waste into the center of the fire-box, the waste being fed into the spout O from an endless belt or apron from the mill, or many other convenient way. The flame from the iirebox A is thrown up against the bottom of the water-pan B by the deflecting-plate D and toward the smoke-stack E, and this also increases the draught. The flues a pass from the front ofthe furnace through the water-jacket B into the irebox A, and are used for starting or stirring the iire, and are closed with the doors b. The doors c open into the ash-pit under the Ere-grate, and are for removing the ashes, &c., from the furnace. From the upper rear end of the deilecting-plate D and on a level therewith the space within the walls is filled with sand or other appropriate material to increascthe draught and carrv the smoke and flame more directly tothe smoke-stack.

One and the main object of having an open pan filled with water and connecting with the water-space around the fire-box is to prevent the generation of steam in a close water-j a cket, while all sparks falling into the water are at once extinguished; and a sheet of water is interposed between the great heat and any surrounding objects, thereby rendering damage from Alire an impossibility.

What we claim as our invention, and desire to secure by Letters Patent, is

1. A refuse-burning furnace, built of brick, the fire-box A of which is surrounded on three sides by a water-jacket, B, connecting with an open Witnesses: Tiros. S. SPRAGUE, MYRON H. CHURCH.
